OK, I have ran into a problem with the attribute-change Preyas. Let's say you are using a Darkus attribute-change Preyas, and you play the ability card “Clean Slate”, which can only be played before you roll a Darkus bakugan. But when you roll your Preyas, when it opens up, it changes to, let's say, Subterra. Technically, you just rolled a Subterra Bakugan, not a Darkus Bakugan. What would hapen then? Would Clean Slates's effect be negated, and all Bakugan are returned to the feild? If you could figure this out, I would like to know.
